darn. given my evo's shift to track days, i'm sold.

 

to be honest ive used chinese ****ty rads for years and the only time ive had them fail is when ive burnt a hole in them from a blown weld on my wastegate exhaust. Ive found for me at least cooling is almost not needed while on track as the air does a good enough job. its when you come in and stop it becomes a problem lol

 

Same here. My radiator is original to the car. I run events with 100*+ temps. So far, not so much as a hiccup, though my cooling system never sees more than 5-7psi and I'm told pressure is what kills the plastic tanks. I do have a used OEM in the garage as back up. I bought it 5yrs ago and haven't had to use it, yet. WooHoo. Of course, with my luck... saying that... *knocking on wood*.

If someone comes up with an aluminum radiator and aftermarket fan that works better than OEM, I'll go that route. I'd actually like to ditch the heavy OEM fan..but it works, so... Or.. if there comes a point OEM is no longer an option for me, then I'd obviously be forced to go aluminum. In the mean time, I'm golden.

 

i thought it does work better than the oem radiator, the question is how much heavier it will be.

 

That's the problem. I had red flag last weekend after 5 laps of chasing and finally passing this M3 into the highest braking/speed zone on the course. 110 track temp. My dual fans were struggling to keep it below 207 while we sat there and baked, highest I've had it ever. I may do more to aid in this when, not if, situation.

 

electric water pump?

 

I haven't read that anywhere, but if true, I would be interested!

 

Had a friend give me a decent hookup on the CSF. I'll post up pics and weights when it arrives.

 

Honestly ive been looking into this!

Weve tried keeping the fans on after stopping etc but cause the water doesn circulate the block water heat soaks, Electric water pump would be perfect. but where do u mount it and do you delete the mechanical pump etc?

 

you going from 100% stock radiator & fan to csf and its fan?

 

Yes. Spal will be wired to stock controller.

 

Yes mech pump gets deleted. There are a few companies that sell delete plates. The electric pump can be mounted anywhere you choose. Definitely buy a quality pump, there's only a handful of names I trust for that.

MAP sells one too as well as a few other evo specialty shops. As for a pump I'd look at Craig Davies, they're pretty much the biggest name in electric water pumps and they're over on your side of the Pacific.

 

yea id go a craig davies. where do you mount the pump itself?

 

You can mount it really almost anywhere. I'd try to find some place on the frame rails that's convenient.

 

is it pretty pnp?
